Let me start this off by saying that I am only a beginner using the ArcHydro tools so I don't have much experience with this toolset. That being said, I have been trying to run the Generate Flow Path tool from ArcToolbox. I believe that I have the necessary inputs setup correctly: Input Batch Point, Input Flow Direction Grid, Input Catchment, and Input Drainage Line. However, whenever I run the tool it gets to around 15% complete and then freezes up on me. At this point I cannot do anything but close ArcMap. I am looking to see if I am doing anything incorrectly and/or anything that I can do to resolve this issue.
Thanks in advance!
